VALVE.

SPECIFICATION forming part of Letters Patent No. 7 58,053, dated April26, 1904;. Application filed May 23, 1903. Serial No. 158,554. (Nomodel.)

To all whom, it may concern:

Be it known that I, JOSEPH ADoLrHE Dns- MARTEAU, a subject of the Kingof Great Britain, residing at Granby, county of Sheiford, Province ofQuebec, Canada,have invented certain new and useful Improvements inValves; and I do hereby declare that the following is afull, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to automatic valves or cocks, and is especiallyadapted for use in connection with flush-tanks used in closets andsimilar situations.

The object of the invention is to produce a device adapted to controlthe inflow of a supply of water to the tank in such a manner as torender the operation substantially noiseless.

The invention consists in the construction and combination of parts, tobe more fully described hereinafter and definitely set forth in theclaims.

In the drawings, which fully illustrate my invention, Figure 1 is alongitudinal section supposed to have been taken through a flushtankwhich is provided with my invention.

Fig. 2 is a vertical cross-section through the cock, the lower portionof the body being shown in elevation. Fig. 3 is substantially alongitudinal vertical section through the cook, a portion of the bodybeing shown in elevation, as in Fig. 2. Fig. 4 is a horizontallongitudinal section showing a portion of the plug broken away. Fig. 5is a perspective of the plug.

Throughout the drawings and specification the same numerals of referencedenote like parts.

Referring more particularly to the parts, 1 represents the flush-tank,from which leads a suitable flush-pipe 2, as indicated, the said tankbeing normally filled or substantially filled with water 3. Preferablylocated near one extremity of the said tank there is provided a pipeconnection or fitting l, the lower portion whereof is threaded, asindicated at 5, for the purpose of attaching to the same a suitablesupply-pipe 5, adapted to conduct water to the flush-tank. The upperportion 6 of this fitting l is provided with a transverse conical bore 7so that this portion 6 constitutes the body of a cock. In this bore 7there is mounted a hollow plug 8, which plug is of conical shape, asindicated, so as to conform to the interior of the bore 7, as shown. Thesaid plug is provided with internal threads 9 at its extremity, whichafford means for the attachment of a keeper or nut 10, which comprises alaterally-disposed annular face 11, which abuts the body adjacent to theextremity of the bore in the manner shown, maintaining the plug inposition in a manner well understood. This nut may be provided with aslot 12, whereby it may be turned by a screwdriver or similar device.The opposite extremity is provided with an integral head 13, whicheffectually closes the interior of the plug at this point, as will bereadily understood, and this head is provided with a transverse threadedopening 14, in which there is mounted a rod or arm 15, which arm hasattached thereto at its extremity a float 16. This float, as shown,consists of an air-tight body formed of light sheet metal. I prefer togive it substantially the form shown, which, it should appear, issubstantially that of a hemisphere, the flat face 17 of the hemispherebeing uppermost, as shown.

Through the lower portion of the wall of the body 6 there is provided anopening or port 18, which is preferably substantially rectangular inform and disposed longitudinally with respect to the axis of the plug,as shown. This port opens communication between the supply-pipe 5 andthe interior of the bore 7 At the side of the body 6 there is providedan outlet-port 19, which is preferably inclined downwardly, as shown,and which is of a form substantially similar to the aforesaid port 18.The plug 8 aforesaid is provided with an opening 20, which may alinewith the said port 19, so as to open communication with the interior ofthe plug, as indicated most clearly in Fig. 2. There are also providedin the lower side of the said plug a plurality of openings 21,preferably of circular form, as shown, and disposed upon a line inclinedwith respect to an element of the conical face of the plug. When theopenings 19 and 20 are in alinement in the manner indicated in Fig. 2,these openings 21 are substantially in alinement with the aforesaid port18. It should be understood that this position of the plug correspondsto the empty position of the flush-tank, and when the plug is in thisposition the float 16 would occupy substantially the position in whichit is shown in dotted outline at 16. When the plug is in this position,water from the supply-pipe will of course flow through the same to fillthe flush-tank, and as the flush-tank fills evidently the float 16willrise with'the waterlevel and will operate the arm 15 in such a manner asto gradually rotate the plug in the direction of the arrow indicatedthereupon in Fig. 2. It should be understood, however, that'even whenthe cock is in its open position the flow through the same is restrictedby reason of the form and arrangement of the aforesaid openings 21,which are, by the way, preferably three in number, as shown. In

this manner while the filling of the tank is effected the violence offlow of the water is impeded to a certain extent, so as to renderfective position, eventually bringing the last of the three openings tosuch a point as to cut off admission of water through the port 18, andwhen this occurs of course the flow of water into the tank ceases.

While I have shown in the accompanying drawings the preferred form of myinvention, it will be'understood that I do not limit myself to theprecise form shown, for many of the details may be changed in form orposition without affecting the operativeness or utility of my invention,and 'I therefore reserve the right to make all such modifications as areincluded within the scope of the following claims or of mechanicalequivalents to the structures set forth.

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. In combination, a body having inlet and outlet ports, and a plugrotatably mounted within said body, said plughaving an inlet, and asingle row of outlets disposed progressively with respect to an elementof its periphery, and so situated that all of the said outlets mayregistcr with said body outlet-port, when the body and plug inlets arein registry, and be closed one by one as the plug is rotated.

2. In combination, a body having a bore, transverse inlet and outletports communicating therewith, and a hollow plug rotatably mounted insaid bore, said plug having a transverse inlet, and a plurality oftransverse outlets disposed progressively with respect to an element ofits periphery, and so situated that all of said outlets may registerwith said body outlet-port when the body and plug inlets are inregistry, and be closed one by one as the plug is rotated.

3. In combination, a body having a conical bore, transverse inlet andoutlet ports communicating therewith, a hollow plug rotatably mounted insaid bore, a floatrigidly attached to said plug, and a tank in whichsaid float lies, said plug having a transverse inlet, and a plurality oftransverse outlets'disposed progressively with respect to an element ofits periphery, and so situated that all of said outlets may registerwith said body outlet-port when the body and plug inlets are inregistry, and be closed one by one as the plug is rotated.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
